In-Depth with Firstbeat: Part 1

: Part 1 of a 3 part super-in-depth review of the Firstbeat system by Jon "Fast Big Dog Schafer". Part 1 introduces the Firstbeat system, part of a growing array of heart-rate variability (HRV ...

Bike Position: Pro Men Conform

: Everybody is different, right? Yes, in a micro sense. But in the macro world it's truer to say everybody is the same, and the pros demonstrate this.

What is Pad Y/X?

: Everybodyís talking about Pad X and Y, or Pad Stack and Reach, in regard to bike fit and selection. What is it? How do you measure it? How is it used?

Real World Yaw Angles

: We routinely see wind tunnel data through a "sweep," that is, from a positive to negative yaw. But what yaws do we actually see in the real world of racing?

Tri Bikes are Too Tall

: Top tri brands make tri bikes that fit marvelously. Today's tri bikes are very good, but they're very uniform, and the lack of variant geometries leaves many riders out.

The Difference A Front-End Makes

: Frame metrics are real, they matter, they tell the truth - stack and reach tell the truth - but they donít tell the entire truth about fit.

Steering Torque and CG

: Steering torque and center-of-gravity have become competing imperatives in bike geometry, with front-center caught in the middle. What's caused this tension? Deep front wheels.

Wheel Torque

: First published 16 years ago, this article by John Cobb on wheel (steering) torque is even more topical today, with the increased use of deep wheels since its first publication.

Tunnel time for Mathias Hecht

: Swiss Pro Mathias Hecht spent time in the EADS wind tunnel in Germany with his sponsor Swiss Side to test his new Canyon and make sure he is ready for 2016.

For want of a saddle

: It's the annual saddle placement rant. You bought a new saddle. Great! But have you accounted for how you sit this saddle? Has it changed your position?

Soup Nazi Solution: TriRig

: Rider needs a long and low geometry. It was the Soup Nazi answer for this guy: No bike for you! Then I remembered the TriRig Alpha series bars, and its online calculator.

HED's Toroidal 2.0 Patent

: HED's new patent claims both a product (rim) and a math problem: a relationship between rim and tire. The patent, announced today, has market implications.

iBikeThief

: There are two technologies that bring an inexpensive, lightweight, long-battery-life, hideable anti-theft bike device within reach.

A Tim Van Berkel bike fit

: Mat Steinmetz of 51 SPEEDSHOP worked with Aussie Tim Van Berkel to dial him in on his new Giant Trinity Advanced Pro 0.

When you are doing it all wrong

: Yesterday our editor-in-chief struggled mightily to mount a tire on a rim, even though he has done it countless times before without problems. But nothing was wrong with the tire or the wheel...

Is your bike safe to ride?

: When I started cycling frame builders did not make frames to destroy them. Today they do. Your frame has a lot of dead cousins or, if not, it should.

Beauty on the inside

: Two frames pop out of the same mold. One is twice as expensive as the other. What justifies the big price variance? Is it all just marketing?

Split-Nose Saddle Case Study

: It's a graphic example of the difference a saddle placement can make. Matt Hansen and Lionel Sanders ride very different positions, the fruit of where their split-nose saddles are mounted.

Change the Saddle, not the Position

: When you swap out a standard for a split-nose you probably donít want to change your position, just your saddle. Letís talk about how you mount a split-nose saddle so that only your saddle, and not ...

The Return of Long and Low?

: For a decade the tri bike has been "rising." The advent of newer aerobars that efficiently pedestal the pad and extension might signal a reversal of that geometric trend.

Speed Wobble

: I expected almost no incidences of speed wobble since the onset of today's monocoque carbon frames. Instead 3 in 10 of you have had speed wobble occur with these bikes.

A Show of Hands?

: Where can you place your hands when riding, and have the bike handle to your liking? Good question, and it's surprising how hard a question this is to answer.
